Except U.S.A., Canada, and Puerto Rico
Use SAE 5W-30 engine oil.
Oil container labels provide important
information.
A chief contribution this type of oil makes
to fuel economy is reducing the amount of
fuel necessary to overcome engine friction.
For maintenance service, Mazda
recommends Mazda Genuine Parts and
Castrol
® (Mexico only).
(ILSAC)
(Mexico)
Use SAE 5W-30 engine oil. If SAE 5W-30
engine oil is not available, use SAE 5W-20

Vehicle Engine Control Unit Reset Procedure
After replacing the engine oil, it is recommended to have a repair shop \
such as an
Authorized Mazda Dealer perform the initialization (engine oil data res\
etting) of the
recorded value. If the value recorded by the computer is not initialized\
, the wrench indicator
light may not turn off or it may turn on earlier than normal.
Refer to Maintenance Monitor on page
6-18.

Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal
operating temperature.
3. Turn it off and wait at least 5 minutes
for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.

MAXOK
MIN
5. Pull it out again and examine the level.
The level is normal if it is between the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not overfill the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is
positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully .
Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before attempting
to work near the cooling fan:Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and
radiator are hot:When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.

Maintenance and Care
Owner Maintenance
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year—at the beginning of the
winter season—and before traveling where
temperatures may drop below freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks
on the coolant reservoir when the engine
is cool.
If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
 Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 Use only soft (demineralized) water in
the coolant mixture. Water that contains
minerals will cut down on the coolant's
effectiveness.
 Do not add only water. Always add a
proper coolant mixture. The engine has aluminum parts and
must be protected by an ethylene-glycol-
based coolant to prevent corrosion and
freezing.
 DO NOT USE coolants Containing
Alcohol, methanol, Borate or Silicate.
These coolants could damage the
cooling system. DO NOT MIX alcohol or methanol with
the coolant. This could damage the
cooling system.
 Do not use a solution that contains more
than 60% antifreeze.
This would reduce effectiveness.
 If the “FL22” mark is shown on or near
the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other
than FL-22 may cause serious damage to
the engine and cooling system.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

Brake/Clutch Fluid
Inspecting Brake/Clutch Fluid
Level
WARNING
If the brake/clutch fluid level is low, have
the brakes inspected:A low brake/clutch fluid level is
dangerous.
A low level could indicate brake lining
wear or a brake system leak which
could cause the brakes to fail and lead
to an accident.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have
the brake/clutch system inspected by an
Authorized Mazda Dealer.
Washer Fluid
Inspecting Washer Fluid Level
WARNING
Use only windshield washer fluid or
plain water in the reservoir: Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
affect your visibility, and could result in
an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather: Operating your vehicle in temperatures
below 4 degrees C (40 degrees F)
using washer fluid without anti-freeze
protection is dangerous as it could
cause impaired windshield vision and
result in an accident. In cold weather,
always use washer fluid with anti-
freeze protection.
NOTE
State or local regulations may restrict the
use of volatile organic compounds (VOCs),
which are commonly used as anti-freeze
agents in washer fluid. A washer fluid with
limited VOC content should be used only
if it provides adequate freeze resistance
for all regions and climates in which the
vehicle will be operated.

Maintenance and Care
Owner Maintenance
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
L
Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.
Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
